This report describes the case of a patient with a supraventricular tachycardia with a ventricular rate of 109/min and no visible P waves in the electrocardiogram. The recording of the monophasic action potential of the right atrium disclosed an atrial tachycardia with a rate of 218/min. There was an alternans of the phase 2 of repolarisation in the action potential. This report emphasises the fact that the phenomenon of alternans occurs in man, as in the experimental animal, at a cellular level.
本报告描述了一名室上性心动过速患者的病例，其心室率为109次/分钟，心电图中未见明显P波。右心房单相动作电位记录显示为房性心动过速，心率为218次/分钟。动作电位复极化2期存在交替现象。本报告强调了交替现象在人体中如同在实验动物中一样，在细胞水平上发生这一事实。
